LINK-HOOK.

SPECIFICATION forming part Of Letters Patent No. 591,951, dated October 19, 1897. Application filed March 11, 1897. Serial No. 626,963. (No model.)

T all whom, it ntay concern.-

Be it known that I, JAMES HARRY 000K, a citizen of the United States, residing at Beech Island, in the county of Aiken and State of South Carolina, have invented certain new and useful Improvements in Link-Hooks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to jointed links that can be easily opened from each other when their component parts are brought in suitable position relatively to each other; and the objects of my invention are to provide a simple and inexpensive link-hook of this class to unite a whiftletree to the clevis of a plowbeam, although it may be used also at the ends of a whiffletree, or to connect the links of an ordinary chain, so that said parts can be quickly and easily united or separated when desired. I attain these objects by the link-hook illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the front portion of a plow-beam and its clevis and the middle portion of a whitfletree united together by means of a link-hook constructed in accordance with my invention. Fig. 2 is a perspective view of the link-hook closed. Fig. 3 is a perspective view of the same shown partly open. Fig. 4 is a top view of the same in a closed position.

In said drawings, A represents a small bar of metal bent in substantially the middle of its length as a staple, to constitute a half-loop a. One end of the bar is bent over to form a loop 64 the end of which abuts upon the loop a. The other end of the bar is slightly flattened and also bent over the top of the loop a to form a comparatively long hook a that leaves a substantially rectangular opening between it and the body a, said opening being preferably slightly narrower adjacent to the end of the hook than in the throat thereof.

The second part of the link-hook consists of a small bar of metal B, bent in substantially the middle of its length, as a staple, to constitute a half-loop b. One end of the bar is bent laterally to form a loop 29 that is interlocked with the loop a of the part A. The other end of the bar B is also bent laterally at b and its end terminates in a head 19 of greater diameter than the width of the opening within the hook a and the length of the neck b under said head 5 is so limited that it cannot escape from the throat of the hook a unless the loop B is turned up and nearly folded back upon the loop A, as shown in Fig. 3. When the neck 12 has been disconnected from the hook, as shown in Fig. 3, it can be swung back and around the loop a as far as desired, and easilyplaced in engagement with the loop of awhiffletree-iron C or the links of a chain. The loop A can also be placed in engagement with the clevis D of a plow or the links of a chain. This connection of parts or their disconnection can be made instantly or within a second of time.

Having now fully described my invention, I claim 1. A link-hook consisting of two metal bars bent in substantially the middle of their length, each bar having one of its ends looped and interlocked with the loop of the other, the loops being at an angle of ninety degrees to each other, one of the bars having also a hook at one end, and the end of the other bar terminating in a laterally-extended neck and a head on the outer end thereof substantially as described.

2. A link-hook consisting of a metal bar bent in substantially the middle of its length, one end being looped on top thereof, and the other end consisting of a hook, bent upwardly, in combination with a bent metal bar one end of which is looped laterally and the other end is provided with a headed neck extended laterally and adapted to be received Within the hook of the other bar substantially as described. r

In testimony whereof I affix my signature in presence of two witnesses.

JAMES HARRY COOK.
